My Android Studio project keeps running my old project/application

I had an Android Studio project I created. The project was named App2-1. After I was done with that project I wanted to move onto my next project named App2-2 that is based off of App2-1. I copied and pasted the directory containing my project "App2-1" and named the new directory "App2-2". Then I opened up the directory using open project in Android Studio. No errors or anything. I made a whole bunch of changes and then I ran the app and it keeps opening my old app. Almost like it has a reference to it or something. Ideas?

Things I've tried:

Restarting Android Studio

Invalidating caches/Restart in AS

Restarted my emulator

Uninstalled my app from emulator/Clean install

Tried a physical device

I'm guessing my workflow of creating a new project based on an old project was incorrect. Appreciate any tips.
